DL-300 Data Logger User Manual Version 1.1.0 Aug. 2015 - 1 -

1. Introduction The DL-300 series is a data logger designed to accurately measure and record the concentration of carbon monoxide/carbon dioxide in the atmosphere, temperature and humidity. It can display the real-time data and log the concentration of CO, CO2, temperature and humidity with a date and time stamp for downloading later. The logging interval is programmable and up to 450,000 data points can be stored in built-in, non-volatile memory.

Users can configure a DL-300 module from the touch screen or via a regular web browser when the module and PC are both connected to the same switch or Ethernet segment. With free iAir app on users’ iOS or Android phones or tablets, they can get the real data over a Wi-Fi network anytime and anywhere. The free DL300 Utility is a convenient software tool to get the real-time data, show run charts and download data from multiple devices running on Windows platform.

The DL-300 series contains RS-485, Ethernet and PoE communication interfaces, the most common communication interfaces in industrial network. It supports a wide operating temperature range of 0 ~ 50°C and easy to be installed by placing on a horizontal surface such as a desktop, mounted on a DIN-rail, or mounted on the wall.

Features

NDIR Sensor NDIR (Non-Dispersion Infrared) is based on one of the natural properties of CO2 molecules: CO2 molecules absorb light at a specific wavelength of 4.26 µm. This wavelength is in the infrared (IR) range. High concentrations of CO2 molecules absorb more light than low concentrations. NDIR sensor can detect fast and accurately in a wide range of CO2 concentration.

Built-in Web Server

With the built-in Web server, users can easily log in to the DL-300 module via a standard web browser to monitor the data and configure the settings without install any software in the terminal.

Get Real-time Data Anywhere and Anytime iAir App for iOS or Android Phones or Tablets is free and easy to install, it can obtain the real-time data from DL-300 modules over a Wi-Fi network anytime and anywhere. The iAir App can link to the DL-300 modules by specifying IP addresses or by searching all the modules connected to the same Ethernet segment.


Data Logging Software The DL300 Utility can be used to configure the modules, monitor real-time data and show the run chart, log alarm events, group DL-300 modules so that the status of distribution groups can be viewed and managed. The utility also allows the log data to be downloaded and exported to a .CSV file that can then be imported into any industry-standard software or spread sheet for analysis.

Easy integration with SCADA software Modbus is one of the most popular protocols used in the industrial world. Supporting traditional serial protocols of RS-485 and Ethernet protocols allow the DL-300 series well-integrated into the HMI/SCADA systems.

Alarm DL-300 series allows users to set high alarm level for CO/CO2/ Temperature/Humidity/Dew Point and low alarm level for Temperature/Humidity/Dew Point, and to enable/disable the alarm functions. An Alarm LED indicator on the front of the DL-300 module will flash when an alarm event is activated, and a relay output related to all alarm events can be use to tap an alarm light/sound or control the IAQ devices such as ventilators, air cleaners, and filters. Beep alarm is available when the CO/CO2 high level alarm occurs. .


Screen Lock Users can secure a DL-300 module by setting a screen lock via the web interface. If the lock is set, users need to enter the correct password when they would like to configure the DL-300 module.

Automatic Baseline Correction The built-in ABC algorithm makes the CO2 sensor on the DL-302 and DL-303 maintenance-free. In most indoor applications, the carbon dioxide level drops to nearly outside air - 400 ppm, and then the ABC algorithm constantly keeps track of the lowest reading and slowly corrects it as the expected fresh air value of 400 ppm.

The ABC algorithm can not apply for the places where are no periods that the CO2 concentration drops to background level such as greenhouses, hospitals, 24-hour operation factories or stories. The ABC function needs be disabled where the spaces the CO2 concentration may be elevated at all times.

Easy Wiring Support for RS-485, Ethernet and Power over Ethernet (PoE) interfaces for users to choose the appropriate one to meet the field requirements.

Power over Ethernet (PoE) The DL-300 series features true IEEE802.3af-compliant (classification, Class 1) PoE technology that allows both power and data to be carried over a single Ethernet cable. PoE provides a unified power system, as well as backup provisions for critical building functions, without any additional cables, outlets or connections. It can reduce the power supply wiring and maintenance costs, and improve system scalability.

Support for MQTT protocol

MQTT is a protocol designed for the efficient exchange of real-time data with sensor and mobile devices. It runs over TCP/IP and is in widest use on the "machine-to-machine" (M2M) and "Internet of Things" applications today

2.4 Cabling for Power and Network

Note

Do not install the DL-300 module near a vent, a ventilation fan or a door where the air flows faster. Also avoid putting the module on a desktop below the nose and mouth to prevent incorrect measurement.

Avoid installing in locations where the temperature is below 0°C or above 50°C. Avoid installing in locations near a strong electromagnetic field.

For connecting with a PC or a Android device

The DL-300 logger can connect to a PoE network without a power source or connect to a non-PoE network. When using the Search function in iAir App on Android or iOS mobile devices, mobile devices need to connect to the same subnet that the DL-300 connected to over Wi-Fi. Similarly to using the Search function in DL-300 Utility running on Windows, the module and the host PC need to connect on the same subnet, too.


The iAir App and DL-300 Utility search the logger by broadcast, therefore only the devices on the same subnet can be searched out. It means that the host PC, Android devices and the logger must have the same broadcast address. The broadcast address for an IPv4 device can be obtained by performing a bitwise OR operation between the bit complement of the subnet mask and the IP address for a device. In other words, take the device's IP address, and set to '1' any bit positions which hold a '0' in the subnet mask.

For example, in an entire IPv4 subnet, the host PC or the Android device uses the private IP address space 172.16.0.0/12 and subnet mask address 255.240.0.0, the broadcast address is 172.16.0.0 | 0.15.255.255 = 172.31.255.255. Only the loggers which have the same broadcast address could be searched out in the iAir App or DL-300 Utility. Please contact with your network administrator to make sure the DL-300 logger is connected to the same sub-network that your Android devices or PC is connected to. For connecting with PC via RS-485 network

The DL-300 logger can connect to the PC through a RS-485 network with power input requirement of +12 ~ +48 VDC.

4.5 MQTT

MQTT stands for MQ Telemetry Transport, it is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. The Publish-Subscribe messaging pattern requires a message broker. The broker is responsible for distributing messages to interested clients based on the topic of a message. Now the MQTT Version 3.1.1 becomes an OASIS standard, it is an ideal protocol for communicating with connected devices in the emerging "machine-to-machine" (M2M) and "Internet of Things" applications, and for mobile applications where bandwidth and battery power are at a premium.

Input the IP address and port number for the MQTT broker and click on the Update Settings button to save the parameters.


- Cycle: sets the time period for update the publish messages in millisecond. - Module Topic Name: sets the module topic name. - CO/CO2/ Relative Humidity/ Temperature (°C)/ Temperature (°F)/ Dew Point (°C)/ Dew Point (°F) Sub Topic Name: sets the sub topic name for each item.

A MQTT client subscribes the messages form a MQTT broker by specifying the topic

name as

Module Topic Name + Sub Topic Name

For example, to subscribe the CO2 level in this case, a MQTT client subscribes the topic name from a MQTT broker as

EtherIO/CO2

Input the Message Attribute Sub Topic Name and Message Sub Topic Name, and then click on the Update Settings button to save the parameters. Users can remotely display message or set the message attribute by publishing MQTT messages to the topic name of [Module Topic Name + Message Sub Topic Name] or [Module Topic Name + Message Attribute Sub Topic Name] - Message Attribute Sub Topic Name: sets the sub topic name for message attribute. If a MQTT message is published to topic name: “Module Topic Name + Message Attribute Sub Topic Name” for a DL-300 logger, the logger will follow the MQTT message described to set the attribute for displaying a message on the screen.

Note: the message attribute needs be passed before the message published to take

the settings effect.


The Attribute message contains 16 hexadecimal numbers separated with comma characters. The following table lists the description of the attribute message. Data Number

0: left-aligned, 1: centered, 2: right-aligned. 16 Sets the text color for the sixth line, ranged from 0 to FFFFFF in RGB triplet


For example, to set the attribute for displaying message by publishing a MQTT message: 1. Topic name: EtherIO/Attr (Module Topic Name + Message Attribute Sub Topic Name)

2. Message content: 0, 0, 0, 8394, 0, FFFFFF, 0, FFFFFF, 0, FFFFFF, 0, FFFFFF, 0, FFFFFF, 0, FFFFFF

It sets the attributes for displaying message with no beep sound, no acknowledge button, no time limit, background , all the lines are left-aligned and white text color.

Note: the message attribute needs be passed before the message published to take

the settings effect.

- Message Sub Topic Name: sets the sub topic name for the message displayed on the screen. When a MQTT message published to “Module Topic Name + Message Sub Topic Name” for a DL-300 logger, the logger will displayed the message.

Note: A message can have a maximum of 6 lines and 14 half-width characters or 7 full-width characters maximum each line. “\r” (0Dh) is used to do a new line.

The example for publishing a MQTT message to display on the DL-300: 1. Topic name: EtherIO/Msg (Module Topic Name + Message Sub Topic Name) 2. Message content: Turn on the ventilation fan.


4.6 I/O Settings

Users can change the temperature unit to Fahrenheit or Celsius in this field.

To Enable/Disable the CO2 Automatic Baseline Correction function. It is supported on the DL-302 and DL-303 only. Q & A Q: What is ABC (Automatic Baseline Correction)? A: ABC stands for the Automatic Baseline Correction which is used to adjust a shifted

baseline to the carbon dioxide level in fresh air. In case of normal indoor application, the carbon dioxide level drops to nearly outside air where there are no human, green plants or anything to elevate the carbon dioxide levels on weekday evenings or weekends, the ABC algorithm constantly keeps track of the lowest reading and slowly corrects it as the expected value in fresh air typically around 400 ppm.

Q: Why I need to enable the ABC? A: When the CO2 concentration detected in a period time of unoccupied space is

greater than the base value of 400ppm, enable the ABC function to adjust the baseline. Be careful that the ABC will not work if a space is constantly occupied such as a hospital, 24-hr factory, 24-hr store, green house or other applications where CO2 levels may be elevated at all times.
